Is there a API for Content Blocks?

Hello,

My localization team has an API that it uses to POST and PUT translations for our knowledge base articles. However, when we try to do that with articles that have content blocks, we are seeing that those articles appear blank if we go to edit them. It seems that when the localization team goes to GET the body of the article, the content blocks are not going with it. Is there an API call available where we can get the content blocks in with the article? If not, is there any other solution for automating content block translations?
Thanks.
